Kratom (Mitragyna speciosa) is a tropical evergreen tree from Southeast Asia and is native to Thailand, Malaysia, Indonesia and Papua New Guinea. Kratom, the original name used in Thailand, is a member of the Rubiaceae family. Other members of the Rubiaceae family include coffee and gardenia. The leaves of kratom are consumed either by chewing, or by drying and smoking, putting into capsules, tablets or extract, or by boiling into a tea. The effects are unique in that stimulation occurs at low doses and opioid-like depressant and euphoric effects occur at higher doses. Common uses include treatment of pain, to help prevent withdrawal from opiates (such as prescription narcotics or heroin), and for mild stimulation.
